Quantifying water contents in the lithospheric mantle is key to our understanding of global geodynamics, composition, and related physical properties. Most lithologies (peridotite) contain little (~50 ppm), but petrological heterogeneities such as pyroxenites are more hydrous (~300 ppm) relative rocks. Pyroxenites also melt at lower temperatures than peridotites thus important magma genesis. Th...

Abstract Hydration, carbonation, and related metasomatism of mantle peridotite play a significant role in the global geochemical cycle. In this study, we combined an analysis carbonated serpentinite with hydrothermal experiments on carbonation Ca-metasomatism for samples from Manlay ophiolite, southern Mongolia to investigate that mechanism body after serpentinization. Samples show was either t...

the main limiting factors in saline-sodic soils are high amounts of salts, low soil organic matter (som) and lowavailability of macro and micro-nutrients. the effect of different amounts of nano iron oxide powder and urban solidwaste compost coated sulfur (uswcs) on the chemical properties of a saline-sodic soil was investigated. the experimentwas conducted using a randomized complete block des...

This study was carried out to determine changes in hydraulic conductivity of a saline sodic soil subjected different wetting-drying cycles and treated wastewater after stabilized sludge sewage gypsum application. In factorial experimental design, the conducted with three replication by using 3 treatment doses (50, 100 150 t ha-1), (0, 7 14 days) 2 water types (fresh wastewater). The values satu...
